Sagiri (狭霧, "Haze"^?) was the sixteenth of twenty-four Fubuki-class destroyer destroyers, built for the Imperial Japanese Navy following World War I. When introduced into service, these ships were the most powerful destroyers in the world. They served as first-line destroyers through the 1930s, and remained formidable weapons systems well into the Pacific War. Sagiri was the first Japanese warship to be sunk during WWII.

Construction of the advanced Fubuki-class destroyers was authorized as part of the Imperial Japanese Navy's expansion program from fiscal 1923, intended to give Japan a qualitative edge with the world's most modern ships. The Fubuki-class had performance that was a quantum leap over previous destroyer designs, so much so that they were designated Special Type destroyers (特型, Tokugata^?). The large size, powerful engines, high speed, large radius of action and unprecedented armament gave these destroyers the firepower similar to many light cruisers in other navies.Sagiri, built at the Uraga Dock Company was the sixth in an improved series, which incorporated a modified gun turret which could elevate her main battery of Type 3 127 mm 50 caliber naval guns to 75° as opposed to the original 40°, thus permitting the guns to be used as dual purpose guns against aircraft.Sagiri was laid down on March 28, 1929, launched on December 23, 1929 and commissioned on January 31, 1930. Originally assigned hull designation "Destroyer No. 50", she was commissioned as Sagiri.
